Nuclear Quadrupole Resonance Study of Chloral Hydrate
Hideaki Chihara,Nobuo Nakamura +1 more
TL;DR: In this paper, three nuclear quadrupole resonance lines were observed in chloral hydrate at temperatures 20-300K, the frequencies being 38.2863±0.0004 MHz(ν1), 39.5415± 0.0002(ν2), and 39.6252± 0.0002(π).

The Redetermination of the Crystal and Molecular Structure of Chloral Hydrate
TL;DR: The crystal structure of chloral hydrate has been determined by the two-dimensional Fourier method and the least-squares method on the NEAC-2203 computer as discussed by the authors, and it is monoclinic and belongs to the P21/c space group, with four molecules in a cell of the dimensions a=11.50,b=6.04,c=9.60A and β=120.

Two-dimensional exchange nuclear quadrupole resonance spectroscopy of molecular crystals
TL;DR: In this paper, a theoretical treatment of the 2D exchange NQR pulse sequence is presented and applied to the quantitative study of exchange processes in molecular crystals, taking into account the off-resonance irradiation, which critically influences the spin dynamics.
